An area firefighter is being held without bail on charges that he had an unlawful online relationship with someone he thought was a 13-year-old girl, authorities said.

An investigation by the Bethlehem and Fairfax County, Va., police departments resulted in the arrest Tuesday morning of Timothy M. Haverly, a 32-year-old firefighter at the Shaker Road-Loudonville Fire Department who volunteers at Delmar Fire Department, police said.

The Delmar man solicited the underage girl in an online chat room and disseminated pornographic images over two weeks of online communications with an undercover officer in Virginia posing as a girl, Bethlehem Detective Sgt. Adam Hornick said Tuesday. Police seized Haverly's computers, he said.

"Our investigation at this point is to determine if there are any local victims," Hornick said.

Haverly is charged with promoting a sexual performance by a child, possessing a sexual performance by a child and attempted dissemination of indecent materials to a minor, all felonies, criminal possession of a weapon and attempted endangering the welfare of a child, both misdemeanors, and unlawful possession of marijuana, a violation, according to police.

He was arraigned in Bethlehem Town Court on Tuesday and taken to the Albany County jail without bail, Hornick said.
